Abstract

Pemuda di lingkungan Perumahan Kota Malang Bagian Barat juga memiliki antusiasme yang tinggi terhadap aplikasi di telepon genggam, laptop, maupun komputer. Namun banyak yang belum menguasai aplikasi-aplikasi yang berkaitan dengan produktivitas yang bisa dipasang di gawai. Pada saat ini, kegiatan di organisasi maupun tugas-tugas di sekolah sangat melibatkan data-data dan angka-angka yang perlu dikelola. Pengolahan data atau angka tersebut bisa sangat sulit dilakukan jika menggunakan aplikasi yang kurang tepat bahkan secara manual. Sebenarnya sudah ada aplikasi yang paling tepat untuk mengolah data dan angka yaitu MS Excel. Aplikasi ini bisa menjadi sangat sulit digunakan jika tidak memahaminya, begitu pula sebaliknya. Berdasarkan kedua kondisi di atas, maka dapat diambil suatu peluang untuk dapat melaksanakan pengabdian pada masyarakat berbentuk pelatihan pengoperasian Microsoft Excel (MS Excel) pada pemuda karang taruna dengan harapan mereka dapat mengenal dan memperoleh pengetahuan di dalam mengoperasikan program komputer berkaitan dengan aplikasi lembar kerja. Sehingga akan mempermudah mereka di dalam mengikuti kegiatan di organisasi maupun dalam menyelesaikan tugas sekolah atau kuliah.

Abstract

Warga Perumahan Permata Bandara Pakis kab. Malang berjumlah sekitar 50 kepala keluarga, namun karena perumahan ini merupakan komplek baru dan ditujukan untuk keluarga baru kepala keluarga yang menempati rumah di komplek tersebut hanya berjumlah 20 kepala keluarga. Kondisi perumahan cukup sepi pada malam hari dan gelap. Mayoritas warga di perumahan permata bandara adalah pekerja kantoran yang lokasi kerjanya berada di kota Malang, Singosari, Lawang, Pandaan, bahkan ada yang di Surabaya. Kondisi ini menyebabkan pada saat mulai gelap yaitu malam hari terkadang warga masih belum sampai di rumah masing – masing sehingga kondisi perumahan sangat gelap. Bahkan pedagang keliling pun masih jarang lewat di sekitaran perumahan karena akses jalan masuk menuju perumahan belum memiliki akses penerangan yang cukup memadai. Instalasi PJU menggunakan saklar otomatis photocell ini merupakan solusi untuk bisa membuat perumahan lebih aman dan nyaman yaitu dengan membuat penerangan jalan yang bisa menyala secara otomatis tanpa perlu ada warga yang harus menyalakan secara manual. Karena penyalaan secara manual oleh warga akan terkendala saat hujan turun dan berbahaya terkena kejut listrik ketika membuka panel listrik utama saat basah. Penamabahan lampu jalan umum di akses menuju perumahan akan membuat pedagang keliling lebih merasa aman dan nyaman untuk melintasi jalan sehingga geliat ekonomi bisa semakin kuat di kawasan ini.

Abstract

Penyulang Pandan Landung merupakan penyulang dengan sistem radial. Dengan sistem radial ini, saat terjadi gangguan dapat diminimalisir dengan penempatan LBS, sedangkan untuk manuver dengan penyulang lain perlu diperhatikan dahulu beban yang dapat ditampung oleh penyulang lain dan jarak lokasi tersebut untuk manuver. Dengan melihat data gangguan yang ada saat ini, penelitian ini bertujuan untuk menganalisis penempatan LBS dalam hal melokalisir atau mempersempit daerah padam. Alternatif penempatan LBS baru dibutuhkan untuk mengurangi daerah padam. Penempatan LBS baru di Penyulang Pandan Landung yakni pada lokasi sebelum trafo R1116. LBS ini memanuver dari Penyulang Pandan Landung ke Penyulang Klayatan sehingga dapat meminimalisir daerah padam pada penyulang Pandan Landung Pandan Landung feeder is a feeder with a radial system. With this radial system, disruption can be minimized by placing LBS, while for maneuvering with other feeders, it is necessary to pay attention to the load that can be accommodated by other feeders and the distance of these locations for maneuvers. By looking at the current disturbance data, this study aims to analyze the placement of the LBS in terms of localizing or narrowing down the blackout areas. An alternative to placing new LBS is needed to reduce blackout areas. The placement of the new LBS at Pandan Landung Feeder is at the location before transformer R1116. This LBS maneuvers from the Pandan Landung feeder to the Klayatan feeder so as to minimize the area of outages in the Pandan Landung feeder. The energy lost before the maneuver is 26987.4 kWh, while when there is a maneuver the value becomes 12647.18, it can be seen that there is a decrease in the value of energy lost by 53.14%.

Abstract

The substation is one of the components of the electric power system that is an important role in the distribution ofelectrical energy and load regulation. In the process of distributing electrical energy, continuity of good service is needed, but theinterferences still often occur, both internal and external. On Sunday, July 21, 2019 there was an interference, Lakarsantri feeder CB failed to trip so make the incoming 20kV CB trip. That interference was caused by the burning of the Switching Substation in the Citraland area. Therefore, a new relay setting is needed as a recommendation to use transformator 2 to avoid the recurrence of a similar fault. The relay settings have shown good results where the working time of the relay on the outgoing feeder side is faster than the incoming feeder 20kV and the incoming transformator 150kV side, when coordination simulated using the E-TAP 12.6.0 software by entering the current setting and the time setting, it shows good coordination because when there is an interference on the outgoing feeder, CB outgoing feeder works first, not the incoming feeder 20kV CB or the incoming transformator 150kV CB. Preventive maintenance on other equipment such as CB and CT need to be be done to increase of equipment reliability to reduce the occurs of protection failure or damage to the equipment.

Abstract

The current transformer is an electric power instrumentation device that functions to change a higher current value to a lower value for protection and measurement purposes. Field conditions and service life cause the current transformer to decrease and not function. Therefore, it is important to do this research to determine the current condition of the current transformer. The method used to obtain current transformer quality indicators is the insulation resistance test method and the tangent delta test method. The results of testing the insulation resistance of current transformers at GI Tanjung Awar Awar Babat in 2020-2021 using the VDE standard (Catalogue 228/4) and IEEE std 43-2000 show that the insulation resistance value of all current transformers has increased by an average of 81900Ω from the previous period but, this value is still in good criteria, namely 170 + 1 MΩ and there is an increase in the current transformer grounding resistance test from the previous period with an average of 0.176 however, according to the PLN book 605.K/DIR/2010 the results of the ground resistance test have good criteria. of < 1. Based on ANSI C 57.12.90 and IEEE C57.152-2013 standards, the tan delta test results are still in good condition because the tan delta value is not more than 0.5%. Current transformer tan delta testing in 2020-2021 has decreased, indicating that the insulation performance of current transformers in 2021 is better than in 2020.

Abstract

Motor induksi merupakan salah satu motor listrik yang luas penggunaannya. Dalam kondisi tertentu motor induksi tak jarang mengalami kerusakan yang disebabkan oleh beban berlebih, hubung singkat di dalam kumparan, maupun kondisi lingkungan yang membuat motor induksi bekerja diluar batas kemampuannya. Salah satu akibat dari kerusakan pada motor induksi adalah kondisi kumparan yang tidak memungkinkan untuk digunakan lagi sehingga harus dilakukan rewinding. Setiap tipe belitan stator motor induksi akan menghasilkan distribusi magnetomotive force (MMF) pada celah udara yang berbeda. MMF yang dihasilkan terdiri dari komponen fundamental dan komponen harmonisanya. Jumlah komponen harmonisa pada distribusi MMF celah udara menimbulkan torsi parasit yang akan berpengaruh pada unjuk kerja motor induksi. Pada penelitian ini akan dilakukan penelitian perbandingan bentuk distribusi MMF celah udara terhadap dua tipe belitan yang berbeda yakni terbagi-screw (Motor A) dan terpusat-terditribusi (Motor B) pada motor induksi 1 fasa dengan kapasitas 1 kW 1000 rpm. Dari analisis harmonisa dan berbeban Motor A memiliki komponen harmonisa lebih tinggi dibanding Motor B sehingga Motor B memiliki peforma yang baik dalam hal torsi sebesar 4,608 Nm dibanding Motor A sebesar 3,37 Nm.
